How to connect to mongoDB on remote server from Angular-Spring application hosted on some other server

Question

My mongoDB is hosted on X box and Angular-Spring Application is on say Y box. When both are on local, my application works fine, but on this server level configuration I'm getting below issue.

HTTP Status 500 - Request processing failed; nested exception is org.springframework.dao.DataAccessResourceFailureException: Unable to connect to any servers; nested exception is com.mongodb.MongoServerSelectionException: Unable to connect to any servers

type Exception report

message Request processing failed; nested exception is org.springframework.dao.DataAccessResourceFailureException: Unable to connect to any servers; nested exception is com.mongodb.MongoServerSelectionException: Unable to connect to any servers

description The server encountered an internal error that prevented it from fulfilling this request.

We have changed configuration to point to X box in all configurations

Answer 1

The error was location of jar file. I'm using Apache tomcat and jar should be kept there. Initially I thought SimpleMongoDbFactory solved my issue, later I realized it was due to jars.

By default, MongoDB bind to local interface only, it will restrict the remote connections. So to publish your remote server and make it available outside of localhost you should update mongod.conf with

bind_ip = 127.0.0.1,192.168.1.1,<remote_server_ip>,....
